IMPROVEMENT lN CHECK-ROW ATTACHMENTS FOR CORN-PLANTERS.

Specification forming part of Letters Patent No. 208,020, datedSeptember 17, 1878; application filed August 14, 1878.

To all whom it may concern:

Be it known that I, ABRAM H. LAW, of Aledo, in the county of Mercer andState of Illinois, have invented certain new and useful Improvements inCheck-Row Attachments for Corn-Planters; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

My invention relates to corn-planters, more particularly to that classof implements known as check-row corn-planters, in which the mechanismfor operating the seed-slides in the hoppers is actuated by means of aknotted cord or wire stretched across the field.

The invention consists in certain new and improved devices andcombinations of devices whereby a reciprocating movement is imparted tothe sliding bar which operates the seedslidesthrough the passage of theknotted cord or wire, in the manner hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a plan view of a corn-planterprovided with my improved check-row devices. Fig. 2 is a side elevationof the same; and Fig. 3, a detached sectional view, showing theoperating devices.

Referring to the parts by letters, A represents the forward and A therear frames of an ordinary two-horse corn-planter, the rear frame beinghinged to the forward frame, A, in the usual manner. 7 B is thedraft-pole, O the rimners or furrow-openers, and D D the seed-hoppers,all said parts being attached to and forming part of the forward frame,A.

E E are the supporting-wheels, which also serve to cover the corn afterit is dropped, said wheels being journaled to the rear frame, A. Adrivers seat (not shown) is also secured to the rear frame, in the usualmanner.

In this class of machines it is customary to provide a seat, locatedbetween the hoppers D D, for the accommodation of the operator, whomoves the sliding bar which actuates the seedslides by means of ahand-lever.

. In my improved machine the necessity for this operator'is' obviated,the necessary motion being given to the sliding bar by means of theknotted cord and mechanism which constitutes my invention, and which Iwill now proceed to describe.

To the sides of the machine, outside of the hoppers and wheels, bars G Gare secured, one on each side, said bars being arranged parallel to eachother and in the line of progression of the machine. Near the ends ofthese bars upwardly-projecting brackets h h are secured, between whichguide-pulleys H are journaled. I I are oscillating bars, arranged abovethe bars G G, having their ends pivoted or journaled in suitablebearings a, secured to said bars G. To the ends of the bars I, at pointsadjacent to the pulleys H,uprights J J are secured, one to one side ofthe bar I, and the other at the opposite end of the bar, to its otherside.

J J are similar uprights, rigidly secured to the bars G at pointsimmediately opposite the uprights J. These uprights J J have beveledgrooves K, of semicircular form, formed on their inner adjacent sides,as clearly shown by Fig. 3 of the drawing.

L L represent rods, which are secured to the central portions of thebars I I, and project downward through slots 1, formed laterally throughthe bars G G, the lower ends of said bars also passing through the endsofthe sliding bar F, to which they are secured.

M represents theknotted wire or cord, which when the machine is in use,is stretched across the field to be planted, the knots m being locatedat proper distances apart, corresponding with the distance between therows of plants. I

The operation of the device is as follows: The wire or cord M beingfirst-stretched across the field, and its ends anchored or secured inany well-known manner, it is passed over the pulleys H, and throughbetween the grooves K of the uprights J J on one side of the machine, asshown by Fig. 1 of 'the drawings, the knots on the cord being of greaterdiameter or size than the grooves K.

As the machine is drawn across the field the knots on the cords, inpassing between the uprights J J, first force the forward upright J toone side, or apart from the corresponding upright J, as shown by dottedlines in Fig.3, thereby oscillating the bar I in one direction, andthrough its rod L imparting a reciprocating motion to the sliding bar F,actuating the seed-slides, and dropping the corn at the re quiredpoints. The knots, in passing between the rear uprights, J J, in asimilar way, cause the bar I to oscillate in the opposite direction, andto move the sliding bar back to its former position, each knot thusimparting a reciprocatin g motion to the sliding bar 1*, and cans ingthe seed-slides to drop the corn at stated intervals apart.

When the machine reaches the end of the field, and is turned around toproceed in the opposite direction, the cord or rope is transferred tothe other side, the stakes or anchors being properly placed, and thenthe machine is ready to proceed and operate as before described.

While it is convenient and desirable to have said operating devices onboth sides of the machine, yet, as will be obvious, only one set ofpulleys and oscillating bar is essential in the operation of check-rowplanting, as described, and it may be attached to the cornplanter insuch a way as to be transferable from one side of the machineto theother when a two-row planter is used, though in singlerow planters itmight be centrally arranged, and even in double-row planters, by the useof suitable guiding-pulleys for the cord or rope. The device might alsobe centrally arranged, so that only one would be required for operatingthe machine. I do not therefore limit myself to the use of two of thecheckrow. attachments herein described, one arranged on each side of thecorn-planter; but

I claim as my invention- 1. A check-row attachment for corn-planters,consisting of the laterally-oscillating bar I, connected with thesliding bar, and operating to impart a reciprocating motion thereto bymeans of a knotted wire or rope, in manner and for the purposesubstantially as specified.

2. The fixed bar G, having uprights J, in combination with theoscillating bar I, having the corresponding uprights J, for imparting areciprocating motion to the sliding bar I, substantially as and for thepurpose specified.

3. The combination of athe fixed bar G, oscillating bar I, uprights J J,and guide-pulleys H, operating substantially as and for the purposespecified.

4. The combination of a sliding bar, F, rod L, oscillating-bar I, fixedbar G, uprights J J, and pulleys H, all operating substantially as andfor the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence oftwo witnesses.
